Chicory was mixed into the coffee as a substitute, adding a slight bitterness and strong aroma. Today it is the factor that contributes to the distinct taste and aroma of authentic South Indian Filter Coffee. The most common coffee to chicory ratio is 80:20. Chicory root is a good source of inulin, a type of prebiotic fibre that may support weight loss and improve gut health. It also contains some manganese and vitamin B6, two nutrients tied to brain health. Research on chicory inulin’s effect on blood sugar is limited, several other studies have shown that it may benefit blood sugar and insulin resistance. Insulin is the hormone that transports sugar from your blood to muscles and tissues, where it can be used as fuel.
